I've installed countless conventional ceiling fans that use a "ball mount" and a special bracket, and also used a junction box designed for ceiling fans.
I have never installed a ceiling hugger fan before, but expect to be doing so in the near future. I haven't bought any yet, so don't know what type of hardware is typically supplied.
Does this type of fan also require a ceiling fan junction box? Is i possible to install one with out that type of box?
TIA
As with most things, there is no "one size fits all". Hugger fans come in a variety of styles, with a variety of mounting options. Most of the ball hung type use a method where the canopy screws directly to the body of the fan, and you eliminate the ball hangar completely. Casablanca uses a special flat canopy with a very short ball hangar. There is also a type where the body of the fan, serves as the canopy, and attaches directly to the ceiling box. This particular type is the easiest to attach to a non ceiling fan support box because it uses a long flat mounting bar, which makes it easy to run screws into any wood framing that may be in the ceiling for additional support. Many fans are designed to be hung from "ceiling fan support boxes", but the Nec doesn't require the use of this type of box. It does require the fans to be independently supported if the box is not rated for the fan. A number of the very heavy Hunter and Casablanca fans require wood framing above the box, and a 3/8" lag bolt run through the back of the box into the framing.

The fans I've been looking at do not appear to use a downrod mount, but rather, the housing is mountded directly to the junction box.

Agreed, and I won't know which I need to do until I open up the existing box and see how it's attached.

Thanks... Yes, I've used this type to replace ordinary junction boxes, especially where there was no access from above. I've also used them to hang especially heavy lighting fixtures. This is a good choice if I find ordinary boxes where I have to install these fans.
Ya just never know what people are gonna do.
Speaking of eye bolts, the old original Hunter fans used a special eye bolt that needed to be screwed through the middle of the junction box for its mounting. Those fan bodies were made from cast iron and weighed in at ~50 lbs.
Those Hunters hung from a hook, 3/8" lag hook. The fan had a stem with a rubber bushing that slid down into the hook. In order to remove the fan from the hook, you had to remove the blades then tilt the fan body towards the ceiling and lift. The only problem, aside from the weight, was that the fans are filled with oil, which promptly spills out as you tilt the fan

Yep, the oil could make a mess, but in operation was one of the best designs in its day. The first one I had was made pre-WWII. It had the adapt-aire blades that allowed you to reverse air flow mechanically. I bought a new one just like it in 1972 before they discontinued the adapt-aire feature.
